How to ingest compressed RDF (gzip / zstd / bzip2) fast in Rust by FUSING decompression with the parallel parse instead of decompress-to-memory-then-parse, and which codec to choose. Use when working on sparq-core's compressed ingest (load_reader_parallel, build_external_ntriples_parallel, sparq-cli's open_reader), choosing gzip vs zstd vs bzip2, deciding whether to build a parallel decompressor, or designing the client decode matrix (Solid/JS). Grounded in this project's MEASURED ~13×…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Fused decompress + parse for RDF ingest Authored from measured research. Source of truth: `research/custom-parsers-baseline.md` (the "Compressed ingest" section + the post-fix measurements) and `research/fast-ingestion.md`. Verify before quoting. ## The headline finding (and the bug it exposed) A naïve **streaming** ingest (decoder → parser, one parse round per `read()`) was measured **3.5–5× SLOWER than just decompressing to RAM first** — the opposite of what streaming should cost. Two compounding causes, both fixed by reusing code that already existed: 1. **Per-`read()` flush bug.** `Graph::load_reader_parallel` flushed a parse+sharded-merge round on *every* `read()` call, and decompressors return small reads (gzip ~0.38 MB/read, zstd ~1.6 MB/read) into its 32 MiB buffer. The parallel parser+merge machinery is amortised for ~32 MiB blocks, not 0.4 MB ones. **Fix: a producer thread that fills the full block across `read()` calls** before handing it to the parser. 2. **No pipelining.** Decode and parse ran additively. **Fix: run decode on its own thread feeding a bounded channel**, so it overlaps the rayon parse + dict …

How to install
mdr add sparq-org/sparq/fused-decompress-parse@sha256:5ee1272dd8cde748The line at the top of this page pins the label git:20261005.afb6bad, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
